Filing a Hawaii state income tax return applies if the taxpayer was a full-year resident of Hawaii for that tax year and the taxpayer is required to file a federal individual income tax return for that tax year. The taxpayer is considered domiciled in Hawaii with a permanent home, to which place the individual has the intention of returning whenever the individual is absent. Hawaii state income tax ranges between 1.4% and 11%, which is administered by the Hawaii Department of Taxation. An individual domiciled outside Hawaii is considered a Hawaii resident if the individual spent more than 200 days in Hawaii. Due date falls on April 20th of the tax year. If the due date falls on a Saturday, Sunday, or federal holiday, the due date is moved to the next business day.
